Barbed tubing connector

A tubing connector for sealingly engaging the end portion of a flexible and somewhat elastic tubing adapted to carry a pressurized fluid, said connector comprising a rigid tubular body having a free end for insertion into said tubing, an endmost barb at said free end and additional longitudinally spaced-apart frusto-conical barbs protruding from the outer surface of said body, all of said barbs being concentric and flaring away from said body free end, the frusto-conical surface of said endmost barb having a peripheral groove and an O-ring engaging said groove and protruding outwardly from said frusto-conical surface, said barbs adapted to be inserted into and expand said tubing end portion, said O-ring then sealing said tubing over said connector and preventing fluid pressure build-up in the portion of said tubing surrounding said barbs, whereby said barbs can resist pull-out of the tubing from said connector, and further including fluid pressure venting means for further preventing fluid pressure build-up in the portion of the tubing surrounding said barbs.
